White Salmon Road 3075 is a pleasant, couple mile long, out-and-back cross-country / Nordic skiing trail in the Mt Baker area. It is noteworthy for its great views of Mt Shuksan and its fairly gradual terrain (except for the very end).
The parking lot is a bit tight and on a sloped surface, so you may need some careful jockeying in slippery conditions. But once on the snow-covered road, it meanders as an un-groomed trail through the forest. In later spring months, the last 1/4 mile can be partially bare and may require getting off your skis for sections, but the final cleared panoramic viewpoint is worth the extra effort.
